This invention pertains to paper windin machines of the type in which the roll 0 paper is supported on and rotated by a pair of drums," and it involves simple and improved means for removing the rolls of paper after they have been wound to the desired diameter.

Pa er winding machines are often of such size t at they form rolls of large dimensions and considerable weight, and the problem (A of removing such rolls from the machine is one that has presented considerable difficulty.

One of the objects of the present invention is to provide a simple, inexpensive, manually operated means of such form that it may be incorporated in new machines or added to old ones, and whereby wound rolls of paper of any size and weight may be conveniently removed from the'machine.

In my improved construction I employ a manually operated roll ejecting lever of the first class which may swing about its fulcrum point and has one end adapted to engage the roll to eject the latter from the machine. As one important feature of my invention I provide adjustable supporting means for the lever fulcrum whereby the lever may be normally held out of the path of the paper, 'but may be brought into proper operative relation with the wound roll to be ejected irrespective of the diameter or length of the latter. I i a The lever is attached permanently to the machine at its fulcrum point and may have its handle end detachably connected to the machine for purposes of aiding in proper support of the lever when it is not in use, and for facilitating the movement of the lever into and out of operating position. After the lever has been brought into operating position, the handle end of the lever may be detached from its support, thus leaving it free to be rocked manually about its fulcrum point for purposes of e ecting a wound roll.

In the accompanying drawings which illustrate a practical embodiment of the invention,

Fig. 1 is a view in end elevation, partly broken away, of a paper winding machine showing; a wound roll of paper in full lines and in icatmg 1n dotted lines the movement of the lever and the paper roll as the latter .is discharged from the machine, and

Fig, 2 1s a fragmentary view artly in elevation, and partlyin section, 0 the roll ejectmg mechanism, viewed in a right angles to the plane of Fig. 1. y

In the type of winder illustrated the roll of paper is wound on mandrel 10 while supported on a pair of winding'drums 11, both of which are driven in the same direction to cause a rotation of the roll. A driven pressure roll, not shown, usually engages the upper side of the roll. As the roll increases 1n size the mandrel moves upwardly, but the roll continues to rest on and be supported by-the winding drums 11. I I

When the roll increases to large diameter it is very hea and considerable difiiculty is encountered 1n getting the roll out of the machine as it must be lifted more or less to get it out of the groove between the drums.

In my improved construction I provide one or more, preferably two, manually operated levers 13 which are pivotally supported in the frame 14 of the machine. When the levers are not in use their upper or handle end may be connected by pins 15 to arms 16, carried by a suitable transversely extending shaft 17 mounted in the upper part of the machine, whereby they normally occupy substantially vertical positions.

Each lever is pivoted at a point adjacent to but spaced from its lower end to an adjustable fulcrum. This is shown as an arm 18 secured to a shaft 19, also mounted in the frames 14 of the machine. The lower or operating end of each lever is in the form 0 a wide paddle or blade 20 so that it will not cut into the paper. The blade or paddle end 20 may be made of a separate iece riveted or bolted to the body of the ever and may have ears or lugs 21 at opposite edges straddling the arm 18 and secured thereto by a pin 22 which forms the fulcrum point.

The fulcrum point 22 of the lever 13 is adjustable toward and away from a finished roll of paper for the purpose of moving the plane at roll on agin end or paddle 20 of the lever which carries a sprocket 27 Passing around the sprockets and 27 is a driving chain 28. By this means the shaft 19 may be rotated and the fulcrum shifted by rotating the shaft 26. v

For rotating the shaft 26 there is provided on the shaft a housing 29 having a pinion 30 mounted therein on a stub shaft 31. Keyed to the shaft 26, and meshing with the pinion 30 is a gear 32, and keyed to a hub extension 33 of the sprocket 27 is a gear 34, which also meshes with the pinion 30. The gears 32 and 34 have slightly different teeth; the shaft 26 is non-rotatable; and the hub extension and sprocket are loose on the shaft. The housing 29 may berotated by means of a suitable handle 35 whereby the pinion 30 will travel around the stationary gear 32 and will be driven thereby. The rotation of the pinion 30 serves to drive the gear 34 and the sprocket 27 at low speed because of the fact that the gears 32 and 34 do not have the same number of teeth. There may be a difference of only one tooth. By this construction of gears and sprocket. and chain drive the shaft 19 may be rotated to move the fulcrum point of the lever slowly and accurately to a position where the roll engaging end of the lever'engages the surface of the roll to be ejected.

To prevent rotation of the housing 29 in a reverse direction during operation of removing the roll from the machine, a pawl 36 is secured to that portion of the handle 35 which extends inwardly of the housing 29. The nose of the pawl is normally maintained in engagement with the teeth of the gear 32 by a spring 37. The pawl may be secured to the handle so that it may be disengaged from the teeth of the gear wheel 32 by rotating the handle about its axis, when it is desired to rotate the housing 29 in the opposite direction to move the roll engaging ends of thelever to a position in which it will not interfere with the winding of a roll. The chain 28 may be kept taut by a suitable idler 38 having an eccentric mounting to provide adjustment.

The device operates in the following manner:

When it is desired to remove a formed roll of paper, such as A, the crank handle 35 is grasped and the housing 29 rotated around the shaft 26, and through the medium of the position.

gears 30, 32 and 3.4, the sprocket 27 is driven, which through the medium of the chain 28, drives the sprocket 25. Driving the sprocket 25 rotates the shaft 19, moving the fulcrum point 22 and the roll engaging ends of the lever 13 against the formed roll of paper. During this movement thelever is suspended from and guided by the arms 16. The lever 13 is then disconnected from the arm 16 by removing the pin 15 so that the lever is free to rock about its fulcrum point. .The operator grasps thelevr 13 near its upper ends and rocks it about its fulcrum point, causing the lower ends of the lever to force the roll of paper from its position between the winding drums 11, to a suitable support which may be in the form of a table or the like, not illustrated.

Due to the fact that the fulcrum is near the lower end of the lever and the handle end is long, great power may be brought to bear. It is also important that the operator may bring the full weight of his body to bear in pulling the lever down. Two men may grasp and pull on the lever at the same time. if necessary.

After the roll has been removed from the machine, the lever is again attached at its upper end to its supporting arm 16. The crank handle 35 is oscillated to disengage the pawl 36 from the teeth of the gear 32 and the housing 29 is rotated to move the arm 18, the fulcrum point 22, and the roll engaging end of the lever to a point where it will not interfere with the subsequent winding of another roll of paper.

By pivotally connecting the upper end of the lever with the swinging arm 16. the pin 15 serves as the fulcrum about which the lever is moved into and out of roll engaging the lever against free swinging movement in the machine when not in use. Inasmuch as the bulk of the weight of the lever 13 is carried by its fulcrum point 22, the arm 16 to which the lever is pivotally mounted, may be of relatively light construction, since this arm is not intended to participate in the operation of removing the finished rolls of pa per from the machine by the lever 13, and is therefore subjected to no great amount of strain.

I have illustrated a pair of levers 13. As their upper and lower ends are connected to parallel shafts they may be adjusted along the shafts to bring them adj acentto the ends, the middle or other portion of the roll irrespective of its length. The machine is usually provided with a slitter for trimming or slitting the paper, but this forms no portion of the machine and has not been illustrated.

It is to be understood that the invention is i It also forms means which hold other forms as rightfully fall within the scope of the appended claims.
